Note: this product is the pattern only. Fully fabricated square to rounds are available here..

The pattern will be supplied in two halves and will include a 50mm straight section on the square end.

Please use the drop down menus below to select the diameter of the round end and the style. There is also the option to include the spot weld laps. When we manufacture square to rounds we always include these laps to join the two halves and to enable the spigot to be attached. Depending on how you intend to use the pattern they may not be required; for example if it is to be used as a template for a heavier gauge steel that you intend to fully weld you won't want the laps.

If you wish to fine-tune the size please use the 'Other info' box below. Unless requested otherwise, the length of the square to round will be determined by us in accordance with standard ductwork specification.

Note that with offset square to rounds the flat side will correspond with the 'width' side. If you require the other side to be the flat side i.e the 'depth' side as shown in the drawing, go back and make the width the depth and vice-versa.
